JOSEPH C. GILRDONE, OF FLEETWOOD, PENNSYLVANIA.

VEHICLE SPRING.

Application led March 6, 1925. Serial No. 13,449.

To all whom z't may concern:

Be it known that I, JOSEPH C. GILAnDoNE, a citizen of the United States, residing' at Fleetwood, in the county of Berks andA State of Pennsylvania, have invented certain new and. useful' Improvements in Vehicle Springs, of which the following isa specilication.

This invention relates to improvements in springs and it is intended more particularly vfor use in connection With vehicle springs made up of a plurality of leaves.

The object in the present invention is to provide a spring of this character 1n which the tendency to squeak is reduced to a' minimuml My invention consists of providing each leaf of the spring with a relatively soft metal strip extending across the leaf at each end, and adapted to contact'with the upper surface of the leaf next to 1t.

The invention is morev fully described in I the following specification and clearly illustrated in the accompanying drawing, in which Figure l is a plan viewof my spring. Figure 2 is a side elevational view thereof. Figure 3 is a sectional view taken through 33 Fig. 1. Figure 4 is a detail view, enlarged, of one of the ends of a leaf ofthe spring.

The numeral 1 designates the spring, which is made up of a plurality of leaves of metal 2, as usual. In my present structure however, I upset theen'ds of each leaf, as indicated at 4, bringing it to an appreciable distance above the surface of the leaf im-y mediately beneath it. Immediately beneath these upsetsgnds, I place a strip of relatively soft metal 5, which is attached to the spring 40 loaf lby means of screws 6 or other suitable means, so that these strips may be removed and replaced when worn.

These strips extend the full Width of the leaf, and when the spring is depressed. as when the load is applied, they Willmmove along the surface of the leaf beneath them but this movementl will be a silent one, due to the soft metal, and, inasmuch as this frictional engagement. of the ends ofrthe spring ,50 leaves with the surfaces of the neXtleaf beneath it, causes the greater part of the so` ca lled squeak in springs, it is evident that with my present structure, this noise will be almost if not entirely eliminated.

This structure will to a very great extent overcome the need of lubricating the springs.

Having thusdescribed my invention, I claim and-desire to secure by Letters Patent Inpa'vehicle spring, a plurality of superimposed plates of spring metal, each plate having both of its ends turned downwardly away from the surface of the, plate next above it, a strip of relatively soft metal, 05 equal in length to the width of the plates, secured to the upper surfaceof each turnedl of a pair of screws, and

end by means 'adapted to bear againstthe surface of the J GSEPH C. GILARDONE.,l
